THROW-OUT MECHANISM ron PRINTING-rams}pELIvEnY.

Application filed May 18, 1923, Serial No. 639,858. Renewed January 10, 1928.

The principal object of this invention is to provide for throwing out from a.deli very device a printed product or the like for inspection or any other purpose without lessening the full number of products contained in the bundles delivered by the delivery mechanism. This provides for rectifying the count so that the counting of the number of products in a bundle will remain accurate, L0 although from time to time one of the products is thrown out and diverted from the bundle to which it would otherwise be delivered.

The invention also involves means whereby the throw-out .device will be kept in inopera-' tive condition ordinarily by very simple means and whereby when released by hand it will be prevented automatically from operating until the fullnumber of products to make a complete bundle have been delivered, or at least started through the delivery mechanism, and then it" will act automatically to divert oneproduct and to prevent the counting of that product. "Thus the number of productsin each bundle is the same no matter whether one is thrown out or not. The invention also involves means for immediately restoring the throw out mechanism to its inoperative condition after a single product has been diverted by it and leaving it in its inoperative position until released thereby by hand. J Additional advantages and features of the I invention will be described hereinafter. Reference isto be had-atri the accompanying drawings, in which I Fig. 1 is an end. elevation of a delivery mechanism provided with apreferred embodiment of this invention; I p

Fig. 2 is a sectional view taken ust inside the frame of the machine andshowingprac-' tically all the elements. except theshafts, in side elevation, and illustrating the posi tion of the parts when the products are being fed through in the normal manner, and

Fig. 3 is a similar View showing the position when the throw-out device is acting to divert a printed product.- It is common to provide .newspaper delivery mechanisms'with a throwout device for diverting a product from the delivery mechanism for inspection and similar purposes. It is also common to providethe def livery mechanism with means for separating the delivered products into bundles of fifty each. This separation is performed in a simple way and permits the operators to take up fifty printed products at a time and thereis no need of counting them. However, so far as I am aware, it has always been necessary to' take a product thrown out ing rollers 1, delivery fans 2.'and guides 3 cooperating with-the fans. The fans are located on a shaft 4 which is driven at a constant speed by. the delivery shaft 5 by means of a chain 6 or other positive drive. These two shafts are positively connected together to have a constant speed ratio. In this case'I have shown it as fifty to eight because fifty'products are to be delivered to form a bundle and there are eight fan blades shown.' On the delivery shaft 5 are pulleys 7 for the delivery tapes 8. These tapes therefore work constantly and uniformly as usual. v H

On the delivery shaft 5 is fixed a ratchet wheel 9 having a number of teeth equal to the number of products to be delivered to form a' bundle, 'fifty being shown. This wheel is keyed to the shaft. Loose on theshaft is encounter disc 10 having a notch 11, in its circumference for the purpose of pushing forward the last two orthree products of a bundle .to separate two bundles in the usual manner on the tapes. p

Adjacent to the counter disc i 12 running across the machine and having thereon a cam lever 13 having a roller thereon and held up against the surface of the count-er disc by a spring 14:. This roller drops into a notch 11 shortly before. a revolution is completed to swing the lever 13 and with it the counter toes 14 which swing .down intov position to separate the products,

10 is a pawl shaft can rotate a short distance without turning the counter disc, the purpose of which will appear hereinafter.

The link 19 is provided witha roller 21 which is capable of engaging the surface of the counter disc and rolling thereon and of moving down into the notch 11 therein to permit the projection 17 to start the operation just described. This link is connectedat the top with a bell crank 22 keyed on a shaft 23. The other end of this bell crank has a roller 24 adapted to engage a cam 25 fixed on the shaft 4 of the fan. This cam 25 is provided witha number of depressions and projections alternately arranged and equal in number to the number of fan blades, eight being shown in the present case. Therefore if the roller 24 is allowed to come into contact with this cam 25, the link 19 would be raised by one of the projections and allowed to be lowered again any time a fan blade moves through a space equal to one-eighth of the circumference. However, in normal action, the roller 24 does not engage the cam 25 because on the shaft 23 is an arm 26 adapted to be held down by a spring 27 but normally held up out of operative position by a spring-pressed hand latch 28 as shown in Fig. 2. When held in this position the roller24 is held away from the lower portion of the cam 25 and the roller 21 is also held up out of contact with the surface of the disc 10. Then the delivery will operate in its ordinary manner without any interference by this mechanism. That operation can be continued as long as desired.

On the shaft 23 is fixed a switch guide 29 to move withthe shaft. In the position shown in Fig. 2 this switch guide is turned down out of the way so that it has no effect. When the operator swings the latch 28 away from the arm 26 the spring 27 will depress that arm and bring the link 19 down so that Y the roller 21 thereon will rest on the surface "o f the counter disc 10. This throws the switch guide 29 up a little but not enough to divert the sheets. Now when the counter discrotates far enough so that the roller 21 enters the notch 11 in its surface the spring 27, which has been under tension all the time, will swing the shaft 23 and bring the link 19 down so that the projection 18 will be in the path of the rotating projection 17 and the latter will come into Contact with it and raise the pawl 15 against-the stop 20 29 is moved up into the position shown in Fig. 3 to divert a printed product on a table 31. At the same time the bell crank 22 swings with the shaft 23 and the roller 24 engages in one of the depressions in the cam 25. But this roll 24 cannot stay in that position any longer than the period required for a fan blade to move from one position, shown in Fig. 3, to the next, that is, long enough to receive a printed product and pass out of receiving position. The next projection on the cam 25 will force the roller 24 outwardly to lift the link 19 and release the pawl 15. This also brings the arm 26 up over the end of the latch 28, the spring 32 of which will restore it to the position shown in Fig. 2, in which the parts of the throw-out are located in inoperative position.

The result of this operation is to provide for the delivery of exactly the desired number of printed products on the tapes 8, no

matter whether the operator manipulatesthe throw-out mechanism or not. In other words, the product of the machine will be constant irrespective of the operation of the throw-out mechanism. The stoppage of the counting disc while one product is thrown out re'tifies the counting. It will be seen also that the operator can release the latch 28 free from the position shown in Fig. 2 at any time. This is purely a hand function, but whenever he does it he has to hold the latch back until the roll 21 enters the notch 11' and the-throw-out mechanism will .be held inoperative until it is automatically loo set into operation by the counter disc.

Thus, the operator cannot control the exact time of operation of the throw-out mechanism. He can only select the particular bundle which is to be finished before a product is thrown out and he can provide for throwing only one product out for each bundle delivered.

Thus the difficulty above explained which has been universal heretofore, as far as I am aware, has been entirely avoided.

Although I have illustrated and described only a single form of the invention, I am aware of the fact that modifications can be made therein and that it can be used for other than printed products by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore, I do not wish to be limited to all the details of construction or to the kind of products operated upon, but what I do claim is l 1. .A delivery mechanism for printed products adapted to deliver a bundle of products and throw out one for inspection and provided with means for rectifying the count, so that each bundle will contain the full number of products desired in one bundle.
